The courtyard façades are more discreet, in keeping with the Berlin building tradition, but at the same time of high-quality design. They have a composite thermal insulation system overlaid with a layer of fine-grained plaster. The ground floor and second floor of the courtyard façades are, like the street façades, clad with natural stone in the case of number 43 and facing brick in the case of number 45; number 44 has a plaster socle zone with high-quality profiling. From the second floor upwards, all buildings have felted plaster flaps as window frames.
